Hi guys.

I really hope someone can help me out here.

I am building the "Smokin' Cigarette" as shown in the thread:

www.modelgasboats.com/forum/28...okin-cigarette/

As you can see on the latest pic the engine is huge and the 3" exhaust is just a few millimeters from parts of the wooden hull.
My plan is to preserve the indside and the outside of the hull with epoxy.
So here is the question:

- What sort of (spray)paint should I use in order to protect the inside woodworks from the heat without bubbeling or catching fire? I am considering using spraypaint for radiators (up to 100 degrees Celsius) or spraypaint for engines and exhausts (up to 650 degrees Celcius). But both types are made for metal.

So the real question is not only which of these paints I should use but also:
- will they fix to the epoxy put on the wood?

Please try to help me out here.

Cheers!

I bring a picture here, so show how close the exhaust will be to wooden parts.

Hi Woodie,
Why don't you just line the inside of the hull where it is close to the pipe with some thin alluminium sheet. This will epoxy to the wood and is easily sprayed with exhaust or engine paint. This can be sprayed either before or after epoxying to the wood. Either that or use some exhaust wrap, you can get it at most auto sport stores.
Hope this helps.

Thanks Moof.

I just found a roll of 2 inch self adhesive aluminum in my toolbox.
I will put this on top of the epoxy and then spray it with some white heat resistant paint. The paint is made for engines and other metal, but I take the chance hoping it will bond to epoxy too.
Cheers!

Hey Woodie, you say the paint is for metal... apply the aluminum strips, paint, then epoxy... Or apply your resin, then add the aluminum and paint... That way, you wouldn't have to worry about the epoxy bubbling...

I think I will test all combinations on a board of plywood. Then use my heat blower on them to see what works the best.

Cheers!
